Sorry, this may be a basic question, but it's been giving me a lot of trouble lately; how do I approach a peach that is spamming turnips? I've tried almost everything, but getting in close and in a position to take control just isn't happening. Any tips?
Ideally, you could be close enough to never let her get the chance to pluck turnips safely. This is the best situation. From that point you have reduced methods of success I believe. The worst situation is when you are forced to deal with turnips when you have other priorities. For example, if you are offstage and need to UpB NOW, but a turnip is in the way you really have no choice except to get hit.
You said spamming turnips. I assume you mean peach is grabbing a turnip and throwing it right away, then grabbing another turnip right away after throwing the first. Or something close to that. In this case, you can simply dash into at the incoming throw and shield the turnip. From there, wavedash out and punish peach with a grab/dtilt or something like that. You have
plenty of time to accomplish this because her grabbing turnip animation is so slow. The only thing you have to worry about at this point is when she finally decides to stop spamming from getting punished.
